Data list:
- Figure 2a: S-matrix "zero-crossing" eigenvalues trajectories in the experiment. Examples of six frequencies are listed. For each frequency, the first column is the real part of the eigenvalue, and the second column is the imaginary part of the eigenvalue.

- Figure 2b: S-matrix "zero-crossing" eigenvalues trajectories in the simulation. Examples of six frequencies are listed. For each frequency, the first column is the real part of the eigenvalue, and the second column is the imaginary part of the eigenvalue.
